Plaintiff should ensure to provide the correct address of the defendant so that the summons are duly served upon the Defendant. The Plaintiff may also seek a permission from the Court under Order V Rule 9A (Dasti summons) to effect service of the summons upon the Defendant on its own to further ensure that the Defendant is duly served.
